A random thing to try.
In the FW16 bios, there is a setting called “USB4 device measured boot”.
It does a lot more than the simple description.
Try turning that on or off, to see if it affects the DEG2 at all in Linux.
There might be a similar setting in the Tuxedo BIOS.
I did end up with some bad news. After a longer game session, Windows locked up too.. but, I’m a Linux support engineer, and know nothing about windows.
I’ll go into event logs later to see what happened.
That being said, apparently there are known issues with the 50 series cards and egpu over USBC (that I found out about.. AFTER I got this card)
Ideally, the framework Dev kit gets a price soon and this becomes a nothing issue for me… But while I have the deg2 I’d love to help debug if framework or amd want / need logs.
I can also file a bug on gitlab but not sure what the best project is for that. I also emailed minisforum… So far, silence.
Not to bother @Mario_Limonciello on a Sunday, but if there is an ideal place to report this, please let me know 
@knipp30
You don’t have to wait for the dev kit.
The community have done a 4i Oculink and a 8i Oculink that you could get now, until the usb 4 starts working.
Regarding quirks:
It seems that there are 3 quirks in drivers/thunderbolt/quirks.c not related to DisplayPort:
quirk_force_power_linkquirk_clx_disablequirk_usb3_maximum_bandwidthquirk_force_power_link forces power to a link controller in case a specific peripheral is connected, so it doesn’t seem like it could help.
quirk_usb3_maximum_bandwidth made me speculate, that maybe when a TB5 peripheral is connected, the host tries to match TB5/USB4v2 transfer rates and as it exceeds its physical capabilities, errors are produced. Therefore, I created a similar quirk for USB4 targeting PCIe tunneling and just in case limiting the bandwidth slightly below the actual USB4 capabilities of 3.6GB/s: patch
The quirk was applied as evidenced by the logs below, but the laptop still rebooted after connecting DEG2 with my 3090.

Next, I tried more aggressive matching of the bandwidth quirk to all ports and also enabled quirk_clx_disable that disables some advanced power management features on some older AMD chipsests: patch and quirk application logs:

…but it also hasn’t changed anything 
Yeah, the deg2 is 4i - I’ll consider that.
The good news? I played for about 3 hours on windows and no crashes.
Also, changing the thunderbolt settings in bios seem to make no difference
Ideally to debug it should be reproduced with a USB4 analyzer connected between the system and the eGPU. Minisforum should have these and be able to do that. They can then tell folks what exactly is going wrong.
Another potentially useful data point would be to look at lspci.exe verbose output for the whole topology in Windows and compare it to lspci output in Linux.
I have emailed Minisforum support, quoted the above message and asked to forward it to their engineers. A few days ago I sent them the link to the kernel.org bug report and they did replied they would forward it to the engineering team, so there’s some chance it will not go to /dev/null… @knipp30 if you did so also, it would probably increase the chances 
Adding the output of “sudo lspci -vvv” and “sudo lspci -n” would help.
Hi! I’m not a Framework user(yet), but I’ve been using the DEG2 dock for about a month now with a 9070XT and I’ve had similar issues. The DEG2 froze up and, even under Windows, completely rebooted the system. These freezes were completely random, sometimes it worked flawlessly for a full day, other times it froze up 4 times a day.
As for Linux, I had zero success running anything for more than 5 minutes before a grey screen took over and then reset the OS.(Tried Bazzite and SteamOS)
All tests were done using the included(and unmarked) TB5 cable, so I’m planning on ordering a certified one to see if it’s any better. I slotted in my old GTX1060, and after a week, it’s been much more stable, only encountered a freeze once, so I’m thinking it’s the amount of data transmitted making it lock up.(Perhaps overheating the dock? CPU temps were monitored at all times and weren’t the cause.)
On Windows or Linux or both?
Also, what CPU do you currently have? (AMD/Intel, what model exactly)
Also the exact laptop model may be helpful.
Cheers!
I’m currently in the process of installing Windows on the Tuxedo laptop again (deleted the previous install a few weeks ago) and will post both lspci and lspci.exe to the kernel.org bug report probably later today
I am guessing that a possible cause might be an incompatibility between TB5 and USB4v1 (Essentially TB3). Incompatibility in the sense of maybe a driver bug. TB5 is relatively new tech.
I have a thunderbolt 3/USB4 device. An NVME SSD in an external enclosure.
When doing lspci -vv
I get the following PCIe related devices:
I think the interesting part is the PCIe bandwidth and lanes.
Either end of the USB4/Thunderbolt link is:
Speed 2.5GT/s, Width x1 ← Based on FIO, this looks about right, but I have been told that the real negotiated speed is not populated into “lspci -vvv output” when using USB4/Thunderbolt, so this is maybe bogus.
The end NVME device is (PCIe-gen4):
LnkSta: Speed 16GT/s, Width x4
Doing a data write test with fio, I get only:
1259993303 bytes / second. Or 1.2 GBytes/s. I would expect closer to 3 GBytes/s.
That is definitely not the 40Gbps that USB4 advertises in boltctl:
│ ├─ rx speed: 40 Gb/s = 2 lanes * 20 Gb/s (Gbits/s)
│ ├─ tx speed: 40 Gb/s = 2 lanes * 20 Gb/s
So, that is why seeing your “sudo lspci -vvv” and “sudo lspci -n” would be so useful.
There is also a possibility of mismatched “MaxPayload”, that the lspci output would help identify.

Thanks for your help and involvement!
Windows only at the moment, I’m quite afraid to connect Nvidia to Linux due to past experiences… 
CPU is AMD Ryzen Z1 Extreme, which is effectively the Ryzen 7 7840U. James mentioned an USB4v1 incompatibility, which is definitely possible, as I’m observing the issues through USB4v1 aswell.
It is also difficult to find good USB4/Thunderbolt cables.
For example, the cables that come with my NVME enclosure generally hardly ever work and result in disconnections from the device. I have a lot of NVME enclosures.
It was only after I purchased about 4 different cables for various web sites, did I finally find a cable that worked reliably. My guess is that cable manufacturers are just lying about the quality of their cables, and the labels they put on them.
It is a shame that we don’t have access to the link training data the USB4 chips do. We could use that to help determine the quality of cables, but lack of datasheets / NDAs on the PCIe hardware prevents that.
I think a useful test would also be trying the DEG2 with an Intel CPU laptop with USB4 ports on Linux, and see if reboots happen or not?
Here is the lspci outputs from Fedora 44:

@James3 for you as well
I wish I had an intel laptop to test with 
It would be helpful if the “lspci.exe” output for Windows, also had the output of “lspci.exe -vv”
Similar to the Linux output in the pastebin you did.
My apologies there
Windows lspci -vvv~~~00:00.0 Host bridge: Advanced Micro Devices, Inc. [AMD] - Pastebin.com
This is lspci -vvv and lspci -n on windows.
Ill stay booted into windows for now if you need anything else
Well, the “lspci -vvv” is definitely different between Windows and Linux.
The speed and amount of PCIe lanes for the eGPU is different for a start.
